  1. Why are Hub Motors Used in Electric Bikes More than Cars?

    The topic covered in this blog might seem new and unusual to some of you, but after reading this, you will understand that it is nothing alien, but it is a fairly old concept. The topic that we will discuss about in this blog is hub motor.

    Let us start with the topic without any further delay.

    Hub motor is the direct assembly of the motor assembly combined with the reducer in the hub. Hub motor is not a novel technology. It is a thing, which is about a century old, to say the least, and it is still extensively used. They are mostly used in the electric bicycles.

    The rear wheel of the e- bicycle is powered by an integrated hub motor. Most of the e- bicycles are driven by this sort of rear wheel hub motor. 

     There is a common question in the minds of the people about hub motors, and that is, why are in-wheel motors so extensively used in e- bicycles but rarely used in cars? The answer to this question is, because e- bicycles are two-wheelers and cars are four-wheelers.

    Due to the fact that, the e- bikes accepts the layout of one front, one rear and two wheels, there is no difference in speeds between the two wheels side by side just as the case in car. 
    Furthermore, the suspension of the e- bike is positioned outside the hub, just like the shock-absorbing hydraulic spring on the rear wheel above, and there is no limitation of space. 

    Consequently, an e-bike can seal the complete package of the wheel hub motor. Like this, a good waterproof and dustproof effect can be attained, and the life of the in-wheel motor can be enhanced. 

    The use of in-wheel motors significantly reduces the body structure of e- bikes, is light and compact, decreases self-weight and surges cruising range. These advantages make e- bicycles show explosive growth, and the value of the hub motors for two-wheelers will grow significantly in the near future.

    Amongst them, the outer rotor adopts a low-speed outer rotor motor, the all-out speed of the motor is 1000-1500r/min, short of a reduction device, and the wheel speed is the same as that of the motor; while the inner rotor adopts a high-velocity inner rotor motor, having a reducer with a fixed transmission ratio, for obtaining higher power density, the motor speed can be as high as 10000r/min. With the initiation of more compact planetary gear reducers, inner-rotor in-wheel motors have more power density than low-speed outer-rotor types.

    Due to being used more in more in electric two-wheelers, the demand for two-wheeler hub motor will be on the rise.
